User questions & answers

Question:	will this work on aluminum
Answer:	would work great for tool boxes very little rubber
Question:	Has anyone used this on a chrime bumper
Answer:	I used this product to line the surface of a sorting table on a crabbing boat. It is holding up very well so far under very rough use. A single can doesn't go very far in terms of area covered.
Question:	Can this be used on stainless steel
Answer:	I used 4-5 cans to get good coverage on the whole frame!
Question:	Will this work well on 3d printed PLA
Answer:	It's a tall can. I used it to spray 7 coats on the underside of the rail on one side of my civic and still have a good amount left. Warning that it does tacky/sticky- even after 48 hrs, and it is meant that way. Contrary to intuition, it was designed to be paintable in this state and will accept your primer then base coat afterwards just fine.

User questions & answers

Question:	Spray on wood
Answer:	I would say no. Now, if you apply a light coat then wipe it off I would say yes. For example, I bought a new riding lawnmower so I heavily sprayed all the metal on the thing. I'm sure there is a level of protection but the thing is it collects dust and dirt terribly and the dirt is difficult to remove as the spray when applied heavy stays tacky. I just bought a honda Rancher but am brain storming what to spray on it to protect it. I live in NW WISCONSIN and years ago sprayed my snow blower. We get snow here and after a year if snow blowing I can still feel the tacky boshield on the metal as i did not do a light spray and wipe off. I have not tried putting on multiple light coats and wiping after each application. That may be an option. I hope that helped.
Question:	Can we apply on top of rust
Answer:	Use this https://www.amazon.com/dp/B001CRETZW/?tag=car-search-20 to paint on rusted surfaces
Question:	How much area does a can cover
Answer:	I would never recommend using WD 40 on your bike parts, especially the chain and derailleur, because dust and sand will adhere to it and it will end up a total sludgy mess. Bioshield is much preferable. I have a very expensive chain on my bike and I use, exclusively, Bioshield. I spray it every 200 or 300 miles, wipe off all of the extra, and wipe it down after every ride. That chain essentially has zero wear after nearly 10,000 miles (I have a very accurate chain wear tool that measures chain stretch). This stuff is superb, all I have used for many years. Once every season I soak the chain in an orange based solvent and clean it with a toothbrush and clean the jockey pulleys, chain rings and cassette. Dry, re-lube the chain with Bioshield, and it will be good to go for the next season.

Product description

3M Professional Grade Rubberized Undercoating 03584 helps protect the undercarriage of cars, trucks, vans and recreational vehicles from both corrosion and abrasion. The coating may also be used to protect wheel wells, quarter panels, interior side of fenders, door skins, under side of the hood and trunk lid, floor pans, and more. The rubberized undercoating also helps deaden noise, allowing for a more pleasant and quieter ride. Protecting your vehicle with an application of rubberized undercoating is advised for long-term protection of the undercarriage. Rubberized undercoating creates a protective barrier that seals out grit, grime and moisture that could otherwise corrode the metal components. This extra protection is a low-cost measure that can pay off by potentially extending the service life of a vehicle.

User questions & answers

Question:	I am considering using this product on my Jeep plastic fenders and bumpers. Has anyone done this
Answer:	I've never done it but don't see any reason not to.
Question:	is the color of this undercoating black? can we spray it directly on the plywood on the undercarrriage of our cargo trailer..stage
Answer:	YES. I DID
Question:	does this cure to a hard finish
Answer:	I used four cans to cover the bottom of an eight foot bed on a 2006 F 250
Question:	Can you spray this over rust? And if you can, won't this spray just coat the rust while the rust eats away the metal underneath
Answer:	I don't like the first answer of "Yes". Boeshield is a parrafin-based, derived from petroleum substance. Here's why. Petroleum based products are flammable. They become less viscous with heat, then begin to smoke with more heat. When you get motor oil on exhaust pipes, it smokes, and motor oil is engineered to resist heat, but not that much heat. There are high temperature paints for use in high temperature applications like this. That would be a much better product to eliminate rust on your exhaust system than Boeshield T-9.

User questions & answers

Question:	What color is it
Answer:	Don't spray it over rust, treat or repair the rust first. More than one undercoating job has actually made rust worse by trapping water and it eats away from the inside out and you'd never know until something falls apart.

Product description

FLUID FILM products offer powerful corrosion protection for all metals and superior lubrication for all moving parts. It is a non-toxic, long lasting, thixotropic liquid that has been used for over fifty years in the highly corrosive marine environment of ships and offshore drilling rigs. More recently they have been introduced and successfully utilized in the aerospace, aircraft and automobile industries as well as for home maintenance. Facilities where they are used include the following: government facilities, commercial fishing concerns, gas companies, agriculture, salt plants, municipal plants, power plants, manufacturing plants and pulp and paper mills. FLUID FILM is formulated from specially processed wool-wax, highly refined petroleum oils and selected agents to provide corrosion control, penetration, metal wetting and water displacement. The long lasting product contains no solvents, will not dry out and will penetrate to the base of all metals, providing corrosion protection from both natural and industrial atmospheres. Heavily corroded and/or frozen parts such as nuts, bolts, shafts, etc. that would normally be damaged during maintenance, can be salvaged by applying FLUID FILM.

User questions & answers

Question:	Is this the same as what is in the aerosol cans? Could I just pour this in a spray bottle? Seems like a better idea to buy a gallon than 10oz can
Answer:	The Loctite 502908 undercoating is black in color.
Question:	Does this product contain silicone
Answer:	I used this to undercoat the cab fenders and running boards on my 49 Chevy pickup but they were steel not sure about plastic.
Question:	what color is this
Answer:	Yes is black sticks to metal pretty good. But you need to let cure 100×.i think will be ok on wood. Maybe light coat first to seal the wood and a heavy coat after

User questions & answers

Question:	Can it be diluted
Answer:	I have no experience with the aerosol cans, but I can tell you that the product in the gallon can has the consistency about like that of sour cream. It is a fairly smooth product with no lumps, and it goes through the spray gun you can get for fluid film on Amazon quite well. So if you have an air comressor, you might just want to bite the bullet and get the spray setup. I have not seen a spray bottle that will spray something as thick as FF, but you might have some industrial version available that I am unaware of.Regards,Grant in Iowa
Question:	My employer bought a 5 gallon pail before, but it was extremely thick like Bag Balm. Is this fluid or thick like that and needs to be cut
Answer:	No. Fluid Film does not contain silicone.
Question:	Is there any kind of prep work involved for existing rust
Answer:	Fluid Film NAS is a light color. Kind of like honey or mustard.
Question:	Does this stuff smell like rank cheese? I have a small, aerosol can of some product by them and it smels like gone bad cheese or toe jam orsomething
Answer:	It can but you will waste a lot of product. Fluid Film is very thick and does not get atomized well in generic spray guns. They put out way too much product in globs. The Fluid Film guns are specifically made just for this thick viscosity product.

User questions & answers

Question:	Can this be used as the product for bare wood underneath an RV? Maybe prime wood first with wood primer then this stuff
Answer:	You can use vegetable oil or WD-40.
Question:	Can this be applied to a painted surface, or is scuffing required
Answer:	That is right for spraying vehicles. It does not need cut, but used with a sprayer with some air pressure on the media as well as at your nozzle. Warm temps help also...
Question:	this says 4 pack, is it really 4 cans at 120 oz each
Answer:	This is not a rust converter, it just coats the surface (like oil). Best practice would be to clean the surface before coating. What compromises you make are up to you.
Question:	Can I paint the frame were the tail pipe runs by the frame front to back
Answer:	Rank cheese? No way, it smells like apples
